Absolutely LOVE these tops. Have always had problems finding tops with longer cuts. These are fabulous! Non-itchy, warm, lightweight, wicking, smooth. First time I tried one, I said I would never go back to synthetics.

    Love the pink color, true to the size chart and very fitted. Was thinner than I was looking for, so think of this more as a true underwear layer.

    The version of this shirt that arrived had short sleeves, despite the description on the www site saying it has long sleeves. So, I sent it back.

    I like this top. It is very very thin and warm. The quality is great and it is merino wool. I have to order another size, smaller. The one I ordered is big for a medium size. (long sleeves and body)

    Not sure what it is about this shirt that left me less than thrilled. The fit is ok (bought Med and I wear size 8/10), but the feel and definitely the color are off to me. I have a lot of Icebreaker stuff and love it, but this is a lightweight top that doesn't quite compare to most other items in their line. :/

    The Siren style is nicely made of great non itchy merino wool, I am usually a size 0 or 2 and the xs is perfect. Runs a bit larger than Smartwool. This style is thin but sometimes a thinner one is what is needed!
